How do i change the dimension back to 2m on the starting cube
It seems like you have two objects &quot;Cube&quot; and &quot;Cube.001&quot;. I assume that the &quot;Cube&quot; has dimensions 2m x 2m x 2m.
The &quot;Cube.001&quot; object consists of two default cubes of size 2m x 2m x 2m but because they are in the same object the object dimensions are calculated from their bounding box as can be seen in attached image. You can separate the cubes in edit mode (select &quot;Cube.001&quot; and press TAB button) by pressing &quot;p&quot; and selecting &quot;By Loose Parts&quot;.
